Multifunction Oven with Steam-Cooking Function: A Buying Guide for Versatile Cooking

A multifunction oven with a steam-cooking function can complement or replace several kitchen appliances: a steam oven, fan oven, grill, air-fryer oven or – depending on the model – even a microwave and rotisserie. However, the wide range of functions makes comparisons more difficult. Many appliances advertise numerous programmes, even though important details such as cooking-chamber capacity, water supply and cleaning requirements are often more decisive in everyday use.

This buying guide from the Joybuy Product Recommendation Officer explains what households, families, keen home cooks and space-conscious consumers should look out for.

Common buying mistakes and marketing pitfalls

1. Lots of programmes, but little usable cooking space

An appliance described as “10-in-1” may offer numerous operating modes, but it still needs enough space for the dishes you want to prepare. A small mini oven may be sufficient for bread rolls and individual portions, while families are more likely to benefit from a cooking chamber of around 20 litres or more.

It is not just the external dimensions that matter, but also:

  • Interior height for casserole dishes and poultry
  • Interior width for baking trays or pizza plates
  • Usable depth when using a rotisserie or grill rack
  • Number and position of shelf levels

2. Steam-cooking function without a well-designed water supply

A steam oven needs a reliable water solution. Some appliances require a container to be filled manually, while others have a removable tank. The key considerations are whether the tank is large enough, easy to access and simple to clean after use.

Steam helps control moisture during cooking. However, this does not automatically mean that every dish will be lower in calories or nutritionally superior. The cooking method, ingredients and portion size remain the deciding factors.

3. Cleaning is underestimated

Steam, grease and crumbs collect on the interior walls, base and accessories. Programmes such as AutoClean or steam-assisted cleaning can soften residue, but they do not replace wiping the appliance afterwards. Removable parts and a smooth interior surface wherever possible can reduce the effort required for cleaning.

The most important parameters when comparing models

Cooking capacity, footprint and ventilation

Before buying, measure the available worktop space carefully. A countertop oven or multifunction microwave also needs clearance from walls and wall units. The manufacturer’s specific requirements are decisive; for example, the Bauknecht MF 259 SG recommends sufficient clearance above, behind and at the sides.

A capacity of 20 to 25 litres is often suitable for smaller households and everyday portions. A 24-litre combination oven may also be designed for several snacks, baked goods or a whole chicken. Its actual suitability depends on the interior dimensions and accessories supplied.

Assess the range of functions realistically

Not every function will be used equally often. So consider whether you really want to use the following operating modes:

  • Steam cooking for vegetables, fish or delicate dishes
  • Steam baking to support moisture levels when baking bread and pastries
  • Fan cooking for even baking and roasting
  • Grill for browning surfaces
  • Air-fryer function with a perforated basket
  • Microwave for reheating and defrosting
  • Rotisserie for poultry or larger roasts
  • Additional programmes such as keeping warm, proving or drying

A microwave with grill and fan cooking is practical if reheating is a priority. If you mainly want to bake and steam-cook, you should pay greater attention to the interior space, temperature control and water handling.

Power, accessories and safety

Wattage indicates the electrical power of individual functions, not necessarily the quality of the cooking results. Several power levels are useful for microwaves, while an adjustable temperature and adequate ventilation are important when using the grill.

You should also look for:

  • Heat-resistant handles and oven gloves
  • Automatic switch-off or overheat protection
  • Easy-to-read controls
  • A suitable baking tray, grill rack, steam container or air-fryer basket
  • Parts that are easy to remove
  • Information about using metal accessories in microwave mode

Steam programmes pose a risk of scalding from escaping hot steam. The door should only be opened after an appropriate cooling or venting period.

How to assess running costs and care

Running costs depend on power, usage time and operating mode. A microwave often heats small portions more quickly than a large oven. Fan cooking and grilling, on the other hand, require a preheating phase. Steam programmes also use water, with consumption depending on the programme and its duration.

Simple routines can help extend the appliance’s service life:

  1. Wipe out the cooking chamber once it has cooled.
  2. Empty and dry the water tank after every use of the steam function.
  3. Check the door seal and ventilation area for steam and grease deposits.
  4. Clean accessories according to the manufacturer’s instructions.
  5. Do not use metal objects in a microwave mode that is unsuitable for them.
  6. Never start an appliance empty in microwave mode.

FAQ about multifunction ovens with steam-cooking functions

How much space does a multifunction oven with a steam-cooking function require?

In addition to the stated external dimensions, you must allow for the ventilation clearance specified by the manufacturer. Also measure the depth of the worktop and check whether the door can be opened fully. A 20- to 25-litre appliance takes up less space than a large built-in oven, but it is not automatically suitable for every baking tin.

Is a steam oven more difficult to clean?

Steam can soften dried-on residue, but it does not remove grease and food remains completely by itself. A removable water tank, smooth interior surfaces and dishwasher-safe accessories can make cleaning easier. After steam cooking, the interior should be ventilated and wiped dry.

How long does a combination oven last?

Service life depends on build quality, frequency of use, care and correct operation. A general figure in years would not be reliable. Look for available spare parts, warranty terms, clear operating instructions and a safe location with adequate ventilation.
